Is a length of two sides of an isosceles triangle is 4 cm and 10 cm then the length of the third side?
The length of the third side of an isosceles triangle with sides 4 cm and 10 cm is 10 cm.
We know that in an isosceles triangle, two sides are equal.
One side of the triangle is 4 cm and the other is 10 cm.
Let us consider the third side to be 4 cm,
then 4 cm + 4cm = 8 cm and it is not greater than the third side 10 cm.
Hence, the third side cannot be 4 cm.
Then the third side can be 10 cm,
therefore, 4 cm + 10 cm = 14 cm > 10cm
and 10 cm + 10 cm = 20 cm > 10 cm.

if f(x) = 2 cot x and g(x) = sin x/2 what is the slope of the line joining (0.f(0)) and (pi,g(pi))?
wow help
The slope of the line joining (0, f(0)) and (π, g(π)) is given as follows:
Undefined.
How to obtain the slope of a linear function?The slope of a linear function, given two points, is given as the division of the change in y by the change in x.
The numeric values for these functions are given as follows:
f(0) = 2 cot(0) = 2 cos(0)/sin(0) = undefined, as sin(0) = 0, and we cannot divide by 0.g(π) = sin (π/2) = 1. the sine of 90 degrees is of one on the trigonometric circle.Hence the points are given as follows:
(0, undefined) and (π, 1).
The undefined point means that there is a vertical asymptote at x = 0, meaning that the change in y is undefined, and thus the slope of the function is also undefined.

Could someone help me with figuring this out?
Josh is talking on the phone to his friend Greg who lives in Europe. Greg is used to describing temperatures in °C, while Josh is used to describing temperatures in °F. Greg can use the formula above to quickly convert the temperatures Josh describes to °C.
How can you rewrite the formula so that Josh can quickly convert the temperatures that Greg describes to °F? Justify your solution method.
Answer:
F = 9/5C +32
Step-by-step explanation:
You want to rearrange C = 5/9(F-32) to make F the subject.
SolutionYou can solve for F the same way you solve any similar 2-step equation:

How will you know if a function increases and decreases?
A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value
As we know a function is nothing but a relation between input values and output values where each input has exactly one output.
Consider a function y = f(x)
For a given function if the value of y increases on increasing the value of x, then the function is an increasing function
If the y-value decreases on increasing the value of x, then the function is a decreasing function.
Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.
If a function is differentiable on an open interval, we calculate the derivative of function f(x)
If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.
If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.
Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

A cargo ship left port a and is headed across the ocean to shipping port b. After one month, the ship stopped at a refueling station along a path described by a vector with components leftanglebracket 14, 23 rightanglebracket. After another month, on the same path, the ship reached port b, twice the distance from port a as the fueling station. What are the characteristics of the vector representing the path of the ship?.
Answer:
Step-by-step explanation:
The vector representing the path of the ship from port A to the refueling station has components <14, 23>, and the vector representing the path from the refueling station to port B has twice the magnitude as the vector from port A to the refueling station.
To find the characteristics of the vector representing the path of the ship from port A to port B, we can add the two vectors together.
The sum of two vectors <a, b> and <c, d> is given by <a+c, b+d>. Therefore, the vector representing the path of the ship from port A to port B is given by:
<14, 23> + 2*<14, 23> = <14+214, 23+223> = <42, 69>
The vector representing the path of the ship from port A to port B is <42, 69>. This vector has a magnitude of √(42^2 + 69^2) = √(1764 + 4761) = √(6525) = 81 and a direction given by the angle theta, where tan(theta) = 69/42.

What is the multiplicity of 0?
The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.
In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.
If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.
In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.

Explanation:
From the question, we were provided the following information:
Miss Meg's initial salary was $450Miss Meg's salary increased to $1760With this information, we will be able to find the percentage of increase in her salary.
__________________________________________________________
Solve:
To find Miss Meg's percentage salary increase, let us first calculate the difference between her new and initial salary.
$1760 - $450 = $1310
We now know that Miss Meg's salary increased by $1310
Using this information, we can then get her salary increase amount and divide it by her original salary.
$1310 ÷ $450 = 2.9111
Multiply 2.911 by 100 to get the decimal into percentage form to show us the percentage salary increase.

A line on a graph is a series of points connected by a straight line. It is used to show continuous change or a relationship between two variables.
A line on a graph is a visual representation of a continuous change or a relationship between two variables. It is made up of a series of points connected by a straight line, making it easy to compare changes in data over a period of time. The points on the line represent the values for the two variables being graphed, with the horizontal axis (x-axis) representing one variable and the vertical axis (y-axis) representing the other. The points on the line can be joined with either a straight line or a curved line, depending on the type of data being graphed. For example, a straight line will be used to show a linear relationship between two variables, while a curved line might be used to show a non-linear relationship. By examining the line, it is possible to determine the rate of change or the correlation between the two variables being graphed.

Lea wants to make two pillows for her new couch. She needs 314 square yards of fabric for the first pillow and 112 square yards of fabric for the second pillow. Lea wants to know how much fabric she will have to buy for both pillows. Which expression represents the total number of square yards of fabric she needs for both pillows?.
The equation for the total square yards of cloth she needs for both pillows is 314+112=426.
The total number of square yards of fabric Lea needs for both pillows is the sum of the fabric needed for the first pillow and the fabric needed for the second pillow. This can be represented by the expression:
314 square yards + 112 square yards = 426 square yards
Therefore, the expression that represents the total number of square yards of fabric Lea needs for both pillows is:
314 + 112 = 426
This expression would simplify to 426 square yards. This expression uses the addition operator (+) to add the two quantities of fabric that Lea needs for each pillow. The result is the total number of square yards of fabric that she needs for both pillows.

The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).
What is the y-intercept of the given equation?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation in the question
2x - y = -3
First, we solve form for y and reorder in slope intercept form.
2x - y = -3
Subtract 2x from both sides
2x - 2x- y = -3 - 2x
- y = -3 - 2x
Divide each term by -1
y = 3 + 2x
Reorder in slope intercept form
y = 2x + 3
To find the y-intercept, replace x with zero and solve for y
y = 2(0) + 3
y = 3
Therefore, the y-intercept is 3.
